About DMS Air Conditioning
We're the Western Sydney team that explains air conditioning properly
Six years of designing custom comfort solutions for families and businesses across Penrith and the Blue Mountains

How we got started
DMS started in 2019 with a straightforward idea: what if an air conditioning company actually took time to understand what people needed, instead of just quoting a system size and moving on?
Daniel grew up in Emu Heights and spent years on large commercial and industrial projects, places like BlueScope Steel and Visy where precision matters and cutting corners creates problems. That experience taught him every space is different, and doing it right the first time saves hassle.
What started as one bloke with commercial expertise has grown into a team of seven. We’ve installed systems in hundreds of Western Sydney homes and continue working on industrial and commercial projects across Sydney. The work has changed and the team has grown, but the approach hasn’t: understand the space, explain the options, design it properly.
What makes us different
We’re not interested in being the biggest air conditioning company in Sydney. We’re interested in being the one that solves your specific problem. That means spending time understanding how you use your space, then designing solutions that work for how you actually live or operate.
Most companies will measure up, quote a system size based on square metres, and that’s it. We apply commercial-grade thinking to every project. We consider which rooms you actually use, when you use them, where the sun hits, how the airflow works. Then we explain why certain solutions make sense for your situation.
You’ll get a detailed commissioning report when we’re done, even for a simple split system. Not because we have to, but because you should know exactly what’s been installed and how it’s set up.

What you can expect from us
We show up when we say we will
Your time matters. If we book a site visit for Tuesday at 10am, we'll be there. If something changes, you'll know before you're waiting around.

Quality work, done properly
We're not the cheapest quote you'll get. We're the team that does it right the first time, which ends up being better value than doing it twice.






Solutions for your specific situation
There's no standard installation template at DMS. We design systems based on how you actually use the space, even if that means thinking outside what's typical.






Local team, local knowledge
We understand Western Sydney summers and we're invested in getting it right for our community.






Your Local Ducted Air Conditioning Specialists


Daniel Spiteri — Founder & Director
Local to Emu Heights, Daniel founded DMS Air Conditioning Solutions in {year} with a vision of bringing commercial-grade expertise to residential installations. His background in both commercial and residential HVAC means he understands how to apply professional techniques to home comfort.


Our Installation Team
Seven experienced technicians, all qualified and continuously trained on the latest installation techniques and manufacturer updates.
Our team brings combined experience of 6+ Years in HVAC installation, with qualifications in both air conditioning and electrical work. That means your installation is handled by people who understand the complete picture, not just one part of it.
How we work with you
We listen first
Before we recommend anything, we need to understand your space and how you use it. We'll ask about your routine, which rooms matter most, what your current system does or doesn't do.






We explain your options
We'll walk through what would actually work for your situation and why. You'll understand the difference between options, why zoning might or might not make sense, what features are worth paying for.


We design it for your space
Every house is different. We'll design ductwork that works with your roof structure, position outlets where they'll be effective, and set up zones based on how you use the rooms.


We install it properly
Our team handles everything: mechanical work, electrical, testing, commissioning. We do it once, we do it right, and you'll get a detailed report of what's been installed.


This approach takes more time upfront but means you get a system designed for your actual needs, installed properly, backed by thorough documentation.

How we work together
Everyone here knows the whole job matters, not just their bit.
The person who designs your system talks to the person who installs it. The technician on-site can call Daniel directly if something’s not right. There’s no “that’s not my department” because there are no departments, just a team working on the same thing.
We meet regularly, talk through projects, and share what we’ve learned. When someone finds a better way to do something, it becomes how we all do it.
What that means for you:
Consistent quality regardless of who’s on your job
Direct communication without layers of management
Problems get solved quickly because the right people are talking
Everyone’s invested in the outcome, not just their task


Ready to talk about your project?
Whether you’re replacing an old system, installing air conditioning for the first time, or dealing with a space that’s never quite comfortable, we’d be happy to explain your options properly.
Remember
We think outside the box. If none of these packages perfectly fit your needs, we’ll create a custom solution just for you.
